Description

technical field [0001] The invention relates to the technical field of cable auxiliary equipment, in particular to a logging cable mud scraping and cleaning device. Background technique [0002] Well logging cable is a cable for electrical equipment in the field of well logging technology. It is used for logging, perforating, coring and other operations of various oil and gas wells. After the cable is used, the soil in the well will adhere to the surface of the cable. In order to To ensure the safety and life of the cable, it is necessary to scrape off the soil on the cable surface in time after the cable is used. Most of the existing logging cable mud scraping devices have complex structures and high production costs. Due to the limitations of the core mud scraper structure The effect of mud scraping is not good, just to scrape mud on the cable, which will cause residual mud and a certain amount of water on the surface of the cable, which will easily lead to cable damage, a...
